Transvaginal registration of urethral sphincter EMG with surface electodes at the anterior vaginal wall has been compared to simultaneous registrations of urethral ring electrode EMG and anal surface electrode EMG in 12 patients. We found that the transvaginal EMG was almost identical to the intraurethral EMG during different pelvic floor muscle activities but differed considerably from the perianal EMG. The clinical applicability was investigated during medium‐fill water cystometry followed by pressure‐flow studies, and in 21 out of 25 patients, a satisfactory EMG was registered.
